Subject: [PATCH] ARM: dts: exynos: Remove 'opp-shared' from Exynos3 bus OPP-tables
Date: Fri, 11 Sep 2020 14:22:20 +0200 [thread overview]
Message-ID: <20200911122220.13698-1-m.szyprowski@samsung.com> (raw)
In-Reply-To: CGME20200911122231eucas1p2c0964f2dc4326522a87fc0571ae58c37@eucas1p2.samsung.com
Commits 1019fe2c7280 ("ARM: dts: exynos: Adjust bus related OPPs to the
values correct for Exynos5422 Odroids") and 9ff416cf45a0 ("ARM: dts:
exynos: Disable frequency scaling for FSYS bus on Odroid XU3 family")
revealed that 'opp-shared' property for the Exynos bus OPPs was used
incorrectly, what had the side-effect of disabling frequency scaling for
the second and latter buses sharing given OPP-table.
Fix this by removing bogus 'opp-shared' properties from Exynos3 bus
OPP-tables. This restores frequency scaling for the following busses:
RightBus, LCD0, FSYS and MFC.
